My girlfriend and I recently came back from our 2nd cruise. We did the MSC Opera a few years ago and we decided to try the NCL Sky since the price at the time was too good to pass up. If after reading, you would like more of an explanation, please feel free to ask away.
Cruise Goal: Get away from the brutal Chicago winter in an active way
Embarkation/Disembarkation: As others have mentioned, we got on and off the ship in a hurry. Our shuttle (SAS) arrived at the port at 12:30 pm, after waiting in terrible traffic. Everyone was really friendly at the port and after going through the porters and security, we were on board within 20 minutes. We tried and enjoyed the champagne, OJ, and some of the desserts from Le Bistro. We chose to carry our own luggage off the ship and we had no problems getting off in 20-25 min. Most of the delay came at customs where people were trying to sneak buffet fruit off the ship.
